Microsoft is skewering Google again with scathing ads that say as much about the dramatic shift in the technology industry's competitive landscape as they do about the animosity between the two rivals.

The missive that began Tuesday marks the third phase in a 5-month-old marketing campaign that Microsoft Corp. derisively calls "Scroogled." The ads, which have appeared online, on television and in print, depict Google as a duplicitous company more interested in increasing profits and power than protecting people's privacy and providing unbiased search results.

This time, Microsoft is vilifying Google Inc. for sharing some of the personal information that it gathers about people who buy applications designed to run on smartphones and tablet computers powered by Google's Android software. Earlier ads have skewered Google's long-running practice of electronically scanning the contents of people's Gmail accounts to help sell ads and attacked a recently introduced policy that requires retailers to pay to appear in the shopping section of Google's dominant search engine.

"We think we have a better alternative that doesn't do these kinds of nefarious things," said Greg Sullivan, Microsoft's senior manager for Windows Phone, the business taking aim at Google's distribution of personal information about buyers of Android apps.

Microsoft's advertising barbs could potentially backfire. Even as they help draw attention to Google practices that may prod some consumers to try different services, they also serve as a reminder of Microsoft's mostly futile - and costly - attempts to trump its rival with more compelling technology.

"It's always the underdog that does negative advertising like this, and there is no doubt that Microsoft is now the underdog," said Jonathan Weber, who has been following Microsoft's "Scroogled" campaign at search consulting firm LunaMetrics.
